Abstract: A surface acoustic wave bandpass electrical filter has double electrode input and output transducers (IP and OP) whose combined amplitude-frequency response has a fundamental passband centred on a frequency f<sub>o</sub> and a corresponding third harmonic passband. An interposed multistrip coupler (MSA2) has strips (ST) with a mark-to-space ratio of one-to-one and a centre-to-centre spacing λ<sub>s2</sub>/2 chosen such that f<sub>o</sub>/f<sub>s2</sub> is in the range 0.80 to 1.14 but excluding substantially <sub>1</sub>.0, whereby a stopband in the amplitude-frequency response of the coupler (MSA2) between 2f<sub>s2</sub> and 4f<sub>s2</sub> suppresses the amplitude-frequency response of the input and output transducers (IP and OP) over a range of frequencies including 3f<sub>o</sub> ± 0.5f<sub>o</sub>.

Abstract: A large lithographic pattern is written as quickly as possible by writing successive subpatterns in a vector scan mode of operation without any interruption between successive subpatterns. This is made possible by arranging the subpatterns so that they are adjacent to each other and are preferably overlapping and by gradually moving the workpiece with respectto the writing field so as to always keep the subpattern being written within the writing field of the beam. The speed and direction of the workpiece movement (relative to the writing field) is not predetermined for all patterns but is controlled instead by the pattern being written. A sparsely written pattern or portion of a pattern is accompanied by a more rapid table movement than what accompanies a densely written pattern or portion of a pattern. This is made possible by embedding pattern determined workpiece movement commands within the pattern defining data. Through the workpiece movement commands, relative movement between the workpiece and the writing field may be continuously controlled with respect to movement direction, velocity and acceleration. 
     Beam source 10 is controllably turned on and off by blanking apparatus 12 and deflected by deflector apparatus 14. The beam is incident on workpiece 18 on table 16. The position of table 16 is detected by X, Y detectors 24, 26 and controlled by X, Y servos 20, 22. Servos 20, 22 are, in turn, contolled from comparator 28 which compares the desired workpiece position obtained from pattern data memory 34 with the actual workpiece position. The pattern data is used to control X, Y deflection drivers 58, 60 together with X Y correction signals from comparator 30 and representing any difference between the workpiece reference position and its actual position.

Abstract: A plurality of carriers (2) for integrated circuit devices are each uniquely coded so as to be recognisable by an automatic decoding apparatus. The devices are tested and the test results accurately correlated with the appropriate devices by recording the test results for each device, reading the identification code for each carrier in the same sequence in which the devices are tested, and then correlating the test results with the device identifications. In one embodiment the carriers are coded by breaking a selected combination of membranes (46) blocking the transmission of light through an array of perforations (40) in each carrier.

Abstract: A bus for coupling a plurality of units in a data processing system for the transfer of information therebetween. The units are coupled in a priority arrangement which is distributed, thereby providing priority logic in each of the units and allowing bus transfer cycles to be generated in an asynchronous manner. Priority is normally granted on the basis of physical position on the bus, highest priority being given to the first unit on the bus and lowest priority being given to the last unit on the bus. Each of the units includes priority logic which includes logic elements for requesting a bus cycle, such request being granted if no other higher priority unit has also requested a bus cycle. The request for and an indication of the grant of the bus cycle are stored in each unit so requesting and being granted the bus cycle respectively; only one such unit is capable of having the grant of a bus cycle at any given time, whereas any number of such units may have their requests pending at any particular time. The present invention provides a modification to the priority logic which allows a lowest priority unit to be physically positioned at other than the last unit position on the common bus.

Abstract: The invention relates to a process for the production of symmetrical monoacetals of aromatic 1,2-diketones starting from the corresponding alphahydroxyketones and to their use as photoinitiators of polymerisation by ultraviolet radiations. 
     According to the process of the invention, protection of the carbonyl group is not operated, and the aromatic alphahydroxyketones react, in the first step of the reaction, with an halogenating agent in presence of N-substituted aliphatic amide or an aliphatic alcohol from 1 to 5 atoms and, in the second step, with an alkaline metal alcoholate or an alcohol. If the carbonylic group is protected, the alphahydroxyketones are first converted into acetals or hydrazones and then into the products of the invention by means of oxidation or acetalisation.

Abstract: When making a sketch by means of a stylus on a drawing surface, the track of the stylus is detected by a measurement system and passed onto a computer, which generates a computer-internal representation of the sketch, which is imaged by means of a plotter without noticeable parallax from behind through a drawing surface onto the latter, and forms the basis of the further development of a design in sequential steps. In this process, each subsequent step proceeds from the exact imaging of the computer-internal representation of the preceding design step. The intelligent drawing-board required for this consists of a drawing machine, a drawing plate, a drawing surface, a plotter, a stylus, a measurement system and a computer as well as, if necessary, a video screen, and the plotter is arranged, seen by the viewer, behind the drawing surface, so that the plotting beam is directed from behind against the drawing surface. <IMAGE>

Abstract: In a closed loop telecommunications system, e.g, for use in a PBX, the loop interconnects a number of nodes each of which serves at least one terminal. The loop includes a long shift register or other storage device via which all messages in the loop pass and which ensures that the loop's time cycle exactly equals the interval between two consecutive speech samples. It also ensures that this cycle time provides an integral number of pulse times. 
     Normal speech connections are set up by circuit- switching in which each call uses one time slot, with the setting up message sent in packet mode from the calling to the called mode. Packet mode uses one or more slots into which a packet is fitted, the slots used to convey a packet being so chosen as not to interfere with any circuit-switched connection.

Abstract: A method of and structure for optical recording by energy-induced homogenization or fractionation is disclosed. When the,method involves fractionation, a film is provided that contains a homogeneous mixture of a matrix material and an incident energy absorbing material. A spot on the film is treated with sufficient energy in the form of electric fields, radiation or heat, or combinations thereof to effect fractionation and/or homogenization of the film which will undergo further physical state transition only under treatment with additional energy. In a preferred embodiment, the fractionation is effected by laser radiation. The laser irradiated spot becomes inhomogeneous and can be detected by the resulting changes in its optical properties. When the method involves homogenization, a film is provided that contains a inhomogenous mixture. The energy treated spot in this case becomes homogeneous without undergoing a phase transition between the amorphous and crystalline phases. Numerous combinations of fractionation and homogenization can result in the writing and erasing of information in a storage device.
